▎ 摘  要

NOVELTY - The thermometer has a hollow shell whose two ends are provided with two optical fiber fixing points. The shell is provided with a slotted cylinder with a concave groove and a pre-stretched optical fiber. The optical fiber is fixedly connected with the slotted cylinder. Two ends of the optical fiber are fixed on the optical fiber fixing points. A middle portion of the optical fiber is provided with an optical fiber grating. A pre-compressed spring is connected between the optical fiber fixing points and the slotted cylinder. The spring makes axial anti-interference capability of a thermometer. A graphene is filled between the shell and the slotted cylinder. USE - Anti-interference ultra-response FBG thermometer. ADVANTAGE - The thermometer has fast temperature response speed, high detection sensitivity, anti-axial strain interference ability, and small size and easy installation. The graphene is filled between the shell and the slotted cylinder so as to improve response speed of the thermometer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for measuring temperature by an anti-interference ultra-response fiber Bragg grating (FBG) thermometer. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an anti-interference ultra-response FBG thermometer.
